FIELD: machine building.
SUBSTANCE: turbine stator section comprises a plurality of blades made from a composite material and comprising fibrous reinforcement compacted with a matrix, first and second platforms. Each blade has an aerodynamic profile, and the platforms have the form of circular arcs and are made of a composite material containing fibrous reinforcement, compacted with a matrix. First and second platforms have openings in which the first and second ends of the blades are engaged, respectively. Each opening in the first platform has a continuous edge, which is in continuous contact with the corresponding first end of the corresponding blade. Openings in the first platform have dimensions larger than the dimensions of the first ends of the blades engaged in said openings, in such a way as to provide clearance between the first end of each blade and the opening. Each first blade end engaged in the opening has dimensions smaller than the dimensions of the blade body in such a way as to define a shoulder extending around said first end. Shoulder has dimensions larger than the dimensions of the openings of the first platform and is in contact with the surface of the first platform. First and second platform and the first and second ends of the blade are formed and placed with the possibility of connection into a spike. Other inventions of the group relate to a method for producing a stator section and a turbine engine stator, as well as a compressor with said stator and a turbine engine having said compressor.
EFFECT: group of inventions provides the increased tightness of the stator of a turbine engine compressor.
